The Uniblitz ES6B is a 6mm bi-stable laser shutter with a very low-profile construction and guaranteed lifetime of 25,000,000 actuations. Its lack of an external protruding actuator makes it very slim and flexible for system integration. Precision exposure control and laser switching are applications that benefit greatly from the precise, highly repeatable characteristics of the ES shutter series.

Bi-stable shutter devices, like the ES6B, require no power to hold the blades in either the open or closed state.
